New Product Recommendation | Application of Low-Voltage MOS in Lithium Battery DC Lawn Mowers
2025-05-23
Lithium-ion battery powered lawn mowers are a type of gardening tool and landscaping equipment used primarily for maintaining lawns, hedges, and protecting flowers and trees, replacing much of the manual labor with mechanized tools. They also feature excellent product characteristics such as being clean and environmentally friendly, low noise, low vibration, simple maintenance, and low operating costs.
Lithium-ion battery powered lawn mowers use lithium-ion batteries as their power source, and generally use brushless DC motors 。Using six N-channel power MOSFETs to form a three-phase full bridge, the controller controls the on and off states of the six MOSFETs to complete the commutation, allowing the motor to rotate as expected.
